CORN-HUSKING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 559,545, dated May 5, 1896.

Application filed November 8, 1895. Serial No. 568,256. (No model.)

To all whom it may concern:

Be it known that we, LE ROY W. STEVENS and LESTER D. SWART, citizens of the United States, residing at Auburn, in the county of Cayuga and State of New York,have invented certain new and useful Improvements inOorn- HuskingMachines and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention consists in the novel features of construction hereinafter described, reference being had to the accompanying drawings, which illustrate one form in which we have contemplated embodying our invention, and said invention is fully disclosed in the following description and claims.

Referring to the said drawings, Figure 1 is an end View of a portion of a corn-husking machine, showing one of the bridge trees for supporting the husking-rolls and the adjusting devices for the movable rolls. Fig. 2 represents a top plan view of the-said bridgetrees. Fig. 3 is a detail view of one of the movable bearings. Fig. 4 represents a top plan view of portions of a pair of our improved husking-rolls. Fig. 5 represents a transverse sectional view of a portion of one of said rolls. Fig. 6 represents the mounting of a single pair of rollers.

In the drawings we have shown such parts of a corn-husking machine as will enable our invention to be clearly understood.

In the drawings, A A represent the stationary husking-rolls constructed according to our invention and supported in stationary bearings at each end in one of the bridgetrees 13, the said bridge-trees being suitably supported in the frame of the machine, a portion of which is shown at G in Fig. 1.

A A represent the movable husking-rolls. The husking-rolls are arranged in pairs, one roll of each pair being supported in stationary bearings and the other in adjustable bearings.

According to our invention we provide pivotally-mounted bearings for the movable rolls, which are adjustable simultaneously by means of a single operating device to adjust all of the movable rolls,and whichallow each of said movable rolls to yield independently in case of a hard substance passing between it and its respective stationary roll. In this instance the bridge-tree B is provided with a series of recesses 19 b to receive the bearings for the movable rolls, and in said recesses are apertures Z) I), extending downward through the bridge-trees to receive the downwardlyextending adj usting-arms with which said bearings are provided, one wall of each of said apertures being provided with a semicylindrical rib b One of the bearings is shown in detail in Fig. 3 and consists of the bearing proper, D, provided with a downwardly-extending arm (1, having a semicylindrical recess 01 therein to engage the rib b of the bridge-tree and having its lower end recessed to form a forked portion d. The bearings are placed in position in the recesses 12 of the bridge-tree the arms 61 extending downwardly through the apertures I) and the rib b of each engaging the recess d of one of said arms, thus forminga pivotal connection between the bearing and the bridge-tree.

E represents a transversely-extending adjusting-rod mounted to slide longitudinally in the frame beneath the bridge-tree, and the slotted or forked portiond of each bearingarm is placed over this rod, as shown in Fig. 1. The adjusting-rod E is provided adjacent to each of said arms (1 with a collar 6, adjustably secured to said rod by means of a setscrew, and between each of said collars and its corresponding arm 02 is interposed a cushion e, which consists, preferably, as shown in this instance, of rubber, although we may use a coiled spring or other cushioning device if found preferable. At one end the rod E is screw-threaded and provided with a screwthreaded hand-wheel E or other operating means for moving said rod longitudinally. It i will be understood that the bridge-trees at both ends of the rolls A A are constructed alike and provided with the adjusting devices just described, so that the movable rolls are adjusted simultaneously by a single adjusting device at each end of said rolls. It will also be seen that by means of the cushions 6 each movable roll is allowed an independent yielding movement to permit the passage of a hard substance when necessary, thus relieving the rolls from strains which they would otherwise have to bear. It will also be seen that the collars 6 can be independently adjusted upon therod E when necessary, as in setting up the machine or at any other time when such independent adjustment may be desirable. The movable bearings of any roll may be removed when desired without disturbing the other rollers by loosening the collars eon the rod E and taking out said bearings.

In Figs. 4 and 5 we have shown ourimproved husking-rollers, each of which is provided with husking-pinsa, projecting beyond the surface of the roll and engaging or corresponding with recesses a in the opposing roll ,which prevent injury to said pins. In Fig. 5 we have shown a portion of one of said rolls, showing the manner of seating the pins therein. The roll is provided at suitable intervals with a recess a of greater diameter at its bottom, as shown, the bottom of the recess being preferably provided with a smaller aperture or recess a In the recess a? is placed an elastic seating for the pin, which consists, preferably, of a plug F of rubber, which is forced into the said recess and is retained therein by the peculiar shape thereof, the mouth of the recess being contracted, as before described. The pin a, which is preferably made in the form of an ordinary screw, is inserted and screwed into the elastic seating F and preferably projects beyond the same into the aperture or recess a in the bottom of the recess a as shown. This screw or pin has a flaring head, the edges of which penetrate the husk and tend to tear it from the ear, during which operation the elastic seating permits a slight yielding of the pin laterally and also outwardly, which renders its operation more effective. The end of the pin will, however, strike against the walls of the aperture or recess a if the pin is drawn laterally too far, thus limiting the movement of the pin. In case the end of the pin strikes a hard substance which passes between the rolls it will be forced inward, but will resume its normal position by reason. of the elastic seating as soon as it disengages the obstruction. It will be apparent that if the pins were seated in such a substance as wood a hard substance would drive them in flush with the surface of the roll and destroy their utility. By the use of the rubber seating the pins are protected from corrosion, and they can be adjusted from time to time to vary the amount projecting beyond the surface of the roll.

hat we claim, and desire to secure by Letters Patent, is
